Résumé : A new method for indoor localization at 60 GHz is proposed. This method is based on the extraction of the TDOA (Time Difference of Arrival), using a MISO system. With this method, unlike conventional TDOA measurements, it is possible to perform communication and localization at the same time by transmitting two identical UWB OFDM signals using two antennas at the TX and extracting TDOA from the interference spectrum of these two signals at the RX. The improvement of the localization precision is also studied via a multi-band approach to use the whole spectrum assigned to 60 GHz communications. This whole study is made within the framework of the WiGig alliance specifications. The simulations performed with commercial software, confirm the theoretical results while experimental measurements are implemented at lower frequencies to prove this approach.
